Element Section Variables

You can request element section variable output to the data, results, or output database file. These variables are available only for beam and shell elements with the exception of STH, which is also available for membrane elements. They are defined for particular elements in the element descriptions in the Abaqus Elements Guide.

Bimoment of beam cross-section. Available only for open-section beam elements.

ESF1
Field: yes  History: yes  .fil: yes  .dat: yes  

Effective axial force for beams and pipes subjected to pressure loading. Available for all stress/displacement procedure types except response spectrum and random response.

SSAVG
Field: yes  History: no  .fil: yes  .dat: yes  

All average shell section stress components.

SSAVGn

All section strain, curvature change, and twist components.

SEn
Field: no  History: yes  .fil: no  .dat: yes  

Section strain component n (n=1,2,3,4,5,6 for shells; n=1,2,3 for beams).

SKn
Field: no  History: yes  .fil: no  .dat: yes

BICURV
Field: yes  History: yes  .fil: no  .dat: yes  

Bicurvature of beam cross-section. Available only for open-section beam elements.

MAXSS
Field: no  History: no  .fil: yes  .dat: yes  

Maximum axial stress on the section. (This variable can be used with the following types of general beam section definitions: standard library cross-sections, linear generalized cross-sections, or meshed cross-sections with specified output section points. If the output section points are specified, the MAXSS output will be the maximum of the stresses at the user-specified points.)

STH
Field: yes  History: yes  .fil: yes  .dat: yes  

Section thickness (current thickness for SAX1, SAX2, SAX2T, S3/S3R, S4, S4R, SAXA1N, SAXA2N, and all membrane elements if the large-displacement formulation is used; initial thickness for all other cases).

SVOL
Field: yes  History: yes  .fil: yes  .dat: yes  

Integrated section volume. (Not available for eigenfrequency extraction, eigenvalue buckling prediction, complex eigenfrequency extraction, or linear dynamics procedures. Available only for continuum and structural elements not using general beam or shell section definitions.)

SPE
Field: yes  History: yes  .fil: yes  .dat: yes  

All generalized plastic strain components. Available only for inelastic nonlinear response in a general beam section.

SPEn
Field: no  History: yes  .fil: no  .dat: yes  

Generalized plastic strain component n (n=1,2,3,4). Representing axial plastic strain, curvature change about the local 1-axis, curvature change about the local 2-axis, and twist of the beam. Available only for inelastic nonlinear response in a general beam section.

SEPE

All equivalent plastic strains. Available only for inelastic nonlinear response in a general beam section.

SEPEn
Field: no  History: yes  .fil: no  .dat: yes  

Equivalent plastic strain component n (n=1,2,3,4). Representing axial plastic strain, curvature change about the local 1-axis, curvature change about the local 2-axis, and twist of the beam. Available only for inelastic nonlinear response in a general beam section.

Frame Elements

SEE
Field: yes  History: yes  .fil: yes  .dat: yes  

All elastic section axial, curvature, and twist strain components.

SEE1
Field: no  History: yes  .fil: no  .dat: yes  

Elastic axial strain component.

SKEn
Field: no  History: yes  .fil: no  .dat: yes  

Elastic section curvature or twist strain component (n=1,2,3).

SEP
Field: yes  History: yes  .fil: yes  .dat: yes  

All plastic axial displacements and rotations at the element's ends. This identifier also provides a yes/no flag telling if the frame element's end section is currently yielding or not (AC YIELD: “actively yielding”; that is, the plastic strain changed during the increment) and a yes/no/na flag telling if buckling occurred in the strut response (AC BUCKL) or is not applicable. AC YIELD and AC BUCKL are not available in the output database.

SEP1
Field: no  History: yes  .fil: no  .dat: yes  

Plastic axial displacement at the element's ends.

SKPn
Field: no  History: yes  .fil: no  .dat: yes  

Plastic rotations, either bending or twisting, at the element's ends (n=1,2,3).

SALPHA
Field: yes  History: yes  .fil: yes  .dat: yes  

All generalized backstress components at the element's ends.

SALPHAn
Field: no  History: yes  .fil: no  .dat: yes  

Generalized backstress at the element's ends (n=1,2,3,4). The first component is the axial section backstress, followed by two bending backstress components and the twist backstress component.
